We look at the division of 77379684 by 145 
Our goal is to divide 77379684 by 145.

Advancing to step 1:
When dividing 7 by 145, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 145

Let's proceed to step 2:
145 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Take the next digit (3) from the dividend and append it to 77, then repeat: 773 / 145

On to step 3:
773 divided by 145 is 5 with a remainder of 48.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 725 from 773 to get 48.
Grab the next digit (7) from the dividend, add it to 48, then carry on: 487 / 145

Let's proceed to step 4:
The number 145 fits into 487 3 times, leaving a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtract 435 from 487 to get 52.
Take the next digit (9) from the dividend and append it to 52, then repeat: 529 / 145

Let's proceed to step 5:
The number 145 fits into 529 3 times, leaving a remainder of 94.
Put 3 as the next digit of the answer. 
Result so far: 533.0
Subtract 435 from 529 to get 94.
Append the next digit (6) from the dividend to 94 and continue with: 946 / 145

Let's proceed to step 6:
145 goes into 946 6 times with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 5336.0
Deduct 870 from 946 and we're left with 76.
Grab the next digit (8) from the dividend, add it to 76, then carry on: 768 / 145

On to step 7:
768 divided by 145 is 5 with a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 53365.0
Subtract 725 from 768 to get 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 145

Moving on to step 8:
434 divided by 145 is 2 with a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 533652.0
Deduct 290 from 434 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 9:
145 can be fit into 1440 9 times, resulting in a remainder of 135.
The next digit of our result is 9. 
Result so far: 533652.9
Subtracting 1305 from 1440 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 10:
If we divide 1350 by 145, we get 9 and a remainder of 45.
The next digit of our result is 9. 
Result so far: 533652.99
Deduct 1305 from 1350 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 533652.99 with a remainder of 0.045.
